MidOpt UV Block A/R Protective Window LP418

Highlights LP418 filters are absorptive filters used to block unwanted ultraviolet (UV) light while allowing high (>90%) visible and near-IR light transmission. Camera sensors typically will have some sensitivity in the UV spectrum. This light can at times be recorded by the camera as if it is blue light, resulting in an exaggerated bluish tint. … Continued

MidOpt Precision Multi-Layer VIS + NIR A/R Coated Glass Protective Window LP389

Highlights LP389 anti-reflection coated windows are optimized for visible AND near-infrared transmission together, making them ideal for use with cameras that are required to operate 24/7, in 3D imaging, and in some LIDAR applications. The substrate material is optically ground and polished B270 crown glass. This results in distortion-free images and excellent transmission over a … Continued

MidOpt Near-IR A/R Coated Glass Protective Window LP347

Highlights LP347 Near-IR Windows are anti-reflection-coated windows that are specifically optimized for near-infrared transmission, while still allowing visible light to pass. These windows are made of optically ground, polished and coated B270 crown glass, and are commonly used as protective cover glasses for cameras used in surveillance, LPR/ANPR and security applications that function primarily in … Continued

MidOpt Germanium DLC Coated LWIR Protective Window LP8000

Highlights The MidOpt LP8000 Germanium Window has a DLC (diamond-like carbon) coating that is abrasion-resistant and can withstand harsh environments. It has a 7.5–12.5 micron useful range and is an ideal protective window for thermal camera enclosures. It also has an anti-reflection coating to maximize transmission when thermal imaging in the LWIR (long-wave infrared).

MidOpt Industrial-Grade Oleophobic A/R Coated Glass Protective Window LP341

Highlights LP341 filters are similar to LP340 antireflection-coated protective windows except that they have the added advantage of an oleophobic coating on one side. They are offered in 1mm or 2mmm thickness. The oleophobic (anti-smudge) coating repels fingerprints, oils and moisture build-up, allowing for far easier cleaning. Frequent, uncontrolled rubbing during attempts to clean deposits … Continued

MidOpt Sapphire Protective Window LP190

Highlights The LP190 Sapphire Protective Window is stronger than standard glass windows. It has a highly-durable surface to withstand harsh environments and is resistant to high impact, chemicals and alkalis. The LP190 Sapphire transmits wavelengths ranging from UV, VIS and short-wave infrared (SWIR).

MidOpt Fused Silica Protective Window LP170

Highlights LP170 fused silica protective windows are made from an ultra-pure, synthetic optical material similar to fused quartz. They offer extremely low thermal expansion, high-resistance to shock, superior scratch resistance and excellent optical properties. They perform well in high-temperature applications, having the ability to withstand temperatures of up to 1100° C. They are also chemical … Continued

MidOpt Fused Silica Multi-Layer Vis A/R Coated Protective Window LP171

Highlights LP171 fused silica protective windows are made from an ultra-pure, synthetic optical material similar to fused quartz. They offer extremely low thermal expansion, high-resistance to shock, superior scratch resistance and excellent optical properties. They perform well in high-temperature applications, having the ability to withstand temperatures of up to 1100° C. They are also chemical … Continued

MidOpt Precision Multi-Layer VIS A/R Coated Glass Protective Window LP345

Highlights LP345 Windows are made from made from precision polished BK7 optical crown glass, resulting in no image distortion and excellent transmission in the visible and near-infrared spectrums. They are environmentally stable, stain-resistant and virtually free of bubbles and inclusions. MidOpt LP345 Windows are precision double-side, “flip” precision ground and polished and are coated on … Continued

MidOpt Borofloat® Oleophobic A/R Coated Protective Window LP286

Highlights LP286 windows are made with high-impact, thermal-resistant Borofloat®, which is transparent in the near-UV, visible, and near-infrared ranges. It has a very low coefficient of thermal expansion and high shock resistance, withstanding temperatures up to 450° C for extended periods of time. Borofloat® is resistant to staining and harsh chemicals such as acids or … Continued
